The Cleanable High Efficiency Filtration device manufactured under the trade mark of CHEAF is a wet collector system which uses either a polymeric, metallic or glass fibre filtration mat to remove submicron particulate matter from the exhaust gas streams. For many applications, the CHEAF unit offers substantially reduced energy consumption over that required for a venturi scrubber on the same application. The CHEAF can be used on a most particulate matter which is not sticky or viscous and which does not deposit scale on the fibre mat.
The two different types of CHEAF are the fully cleanable type and the renewable media type. Fully cleanable CHEAF units can be used
| • |
On dust emissions in the mineral and mining industries, |
| • |
On inorganic chemicals, dryers and calciners, |
| • |
On prill tower emissions in the manufacture of ammonium nitrate and urea. |
| • |
For spray dryer emissions in the food products and flavouring industries and |
| • |
The perfume manufacturing industries. |
Where acidic emissions are encountered, the renewable media CHEAF unit is used. These industries include
| • |
Container glass and plate glass manufacturing |
| • |
Furnace grade phosphorous manufacturing |
| • |
Galvanizing emissions and several others |
| |
|
Single units of CHEAF can be built to handle gas flows up to 680000 m3/hr (400000 acfm).
The typical areas of applications of the CHEAF units are:
